To allow quiet and smooth operation by suppressing noise following the reciprocation of a cutter to improve operation feeling.

A reciprocation type electric razor reciprocates the cutter (54) while making slide contact with the inner surface of a foil (10) with an inverted U-shape from the side view. The reciprocation type electric razor includes an oscillator (30) reciprocatingly driven by a motor (16) in the main body, a center shaft (52) implanted in the oscillator (30) and raised toward the foil (10), a cutter holder (62) held by the center shaft (52) so as to slide in the axial direction and holding the cutter (54) so as to rock around the axis orthogonal to the reciprocating direction of the cutter, and a spring (74) mounted between the oscillator (30) and the cutter holder (62) so as to be contracted.
